Small particles help to decrease the gas velocity and increase the gas residence in the bed，resulting in better adsorption and separation consequently.

Six pure liquids，namely，water，ethanol，normal propyl alcohol，isopropyl alcohol，acetic acid，and acetone，were selected to be the experimental subjects of this research. Each one-component vapor-liquid equilibrium system was placed in a customized vessel and then rotated at a constant-temperature water bath shaking table.

In this paper，we elaborated the application of Ionic liquids (ILs) in oil desulphurization，including influence factors，desulphurization mechanism，the methods of ILs in oil desulphurization and a novel ILs—immobilized ILs. ILs has unique chemical structure and excellent physical and chemical properties，which show excellent performance in oil desulphurization，compared with other organic solvents. Especially when combined with other processes (such as oxidation)，the desulphurization effect of ILs is better. As ILs is expensive and cannot be completely separated from oil，its industrial application is thus limited. Immobilized ILs can overcome these problems; the development of the immobilized ILs has great potential in oil desulphurization.

Energy integration can not only improve energy efficiency，but also reduce water consumption and CO2 emissions. In this paper，the most practical process integration method - pinch technology-was used to optimize the existing heat exchanger network of an acetone-benzol dewaxing device. The unreasonable heat exchange and minimum utility consumption were identified. It was calculated that the energy-saving potential was about 4228.3 kW. The final retrofit scheme was based on the re-matching of several streams. The retrofit scheme for the heat exchanger network can save 1456.4 kW of heating utility and 524.2 kW of cold utility. The economic analysis of the optimized network showed that the energy cost can be reduced by 2.785 million RMB/yr，waste water productions can be reduced by 3000 tons/yr and the amount of CO2 emission can be reduced by 9078.2 tons/yr. According to the above analysis，optimizing the heat exchanger network can lead to remarkable water saving and CO2 emissions reduction. This study demonstrated that systematic analysis and optimization of an existing acetone-benzol dewaxing device could provide a practical way to improve energy utilization efficiency and reduce resource consumption.

Operating cost was balanced with the lost production penalty due to equipment failures. Compared to the traditional method，the novel framework can obtain a lower total cost.

A study on chemical stripping technology was carried out in a small fixed-fluidized bed，using Daqing crude oil mixed with vacuum residue or FCC slurry as feedstock. Relative gas yield，relative coke decrement and coke content were used to evaluate stripping efficiency. Product components and stripping efficiency of chemical stripping technology and vapor stripping technology were experimentally compared.

The stripping temperature growth of heavy feedstock is lower than that of the light one，when increasing the temperature and ratio of adding regenerant. With chemical stripping technology，the stripping efficiency increased by 20%，coke content of regenerated catalyst decreased by not less than 7%.
